It´s such a bad bug!

Like Watchdogs Legion, Assassins Creed Valhalla crashed and after the crash i saw, that all savegames i made through writing over an old one, got destroyed instandly.
But if i made a new one, everything was ok.
A short time after that, i had to force ASC Valhalla to close down. First evreything but writing over old saves worked out fine, but after a few hours, every savegame but the exclusive ones, where destroyed.
The NEW and all the OLD save files! Every single one AFTER the bug happened the first time, except two other corrupted files, but I´m not totally sure if they really where from before the bug.

Now tIhe game is unplayable for me, because exclusive saves are totally rare. They´re just made when episodic things are going to happen.
Repairing the game files did nothig for the better. Now im trying to reinstall the whole game, but I fear that the only thing that would help will be, to go back through the old files till the first point before the bug, to play the game all over again from there...
But who could tell me, that it wont happen again?

Ubisoft... savegame bugs are a no go... Arent you testing the game well? These kind of bugs must be solved bevore the game is getting released not after!
ASC games are games with hours of gameplay. Players are running around for hours, just to find ressources or good loot. From 10 hours of gameplay i will have to redo more than 5.
After wd legion has got the exact same problems thats not acceptable.

The fans are paying so much money to play the game from the release day on and we know that there will be bugs, but thats simple a game braker and not just a bug.
Please ubisoft! It has to be solved as soon as possible!
